Accumulation (geosciences)

from Wikipedia, the free encyclopedia

Accumulation (Latin accumulare = to pile up, to pile up) is the accumulation, storage, accumulation, deposition of sediments . Most of these deposits are made by the sea or rivers, which deposit loose sediments ( sand , gravel ). The accumulation depends on the flow velocity, grain size, gradient, flow rate, material load , friction , channel cross-section and turbulence .

In glacial morphology (describes surface formation by glaciers and their meltwater) one differentiates between the following forms of accumulation:

Accumulation is also called the accumulation of snow masses on a glacier and the subsequent formation of new ice.

In meteorology is called accumulation, the accumulation or deposit of snow in the lee of rocks, trees or buildings or the formation of snow cornices .

In soil science , the concept of accumulation is also extended to the accumulation of water in the soil with a suitable morphology.

In climatology , the accumulation of CO² in the earth's atmosphere plays an important role in climate change .
